尊敬的先生：在估计生物膜中的孔的导电性时，小圆孔的接触阻力具有一定的重要性(Hille，1968,1970)。这种阻力通常被近似为对与气孔相同半径的半球的会聚阻力。该近似假定半球本身的贡献可以忽略不计。事实证明，这不是真的，半球的阻力实际上与材料在半球外半空间的阻力具有相同的数量级。
Dear Sir: The access resistance of a small circular pore is of some importance in estimating the conductance of pores in biological membranes (Hille, 1968, 1970). This resistance is usually approximated as the convergence resistance to a hemisphere of the same radius as the pore. The approximation assumes that the contribution of the hemisphere itself is negligible. It turns out that this is not true and that the resistance of the hemisphere is in fact of the same order of magnitude as the resistance of the material in the halfspace outside the hemisphere.
